The 3-way tray technique is popular as it provides master and opposing arch impressions and an interocclusal record at the same time. Excellent clinical results can be achieved with appropriate case selection, use of rigid tray and impression materials, attention to tray positioning and other details throughout the process, and clear understanding of the limitations of the technique by the oper...

We describe an approach to automatic parallelisation of programs written in Sieve C++ (Codeplay’s C++ extension), using the Sieve compiler and runtime system. In Sieve C++, the programmer encloses a performance-critical region of code in a sieve block, thereby instructing the compiler to delay sideeffects until the end of the block. The Sieve system partitions code inside a sieve block into ind...

We modelled the financial and environmental costs of two commonly used anaesthetic plastic drug trays. We proposed that, compared with single-use trays, reusable trays are less expensive, consume less water and produce less carbon dioxide, and that routinely adding cotton and paper increases financial and environmental costs. We used life cycle assessment to model the financial and environmenta...

Shortcut methods are valuable tools in the early stages of chemical process design, where numerous flowsheet alternatives need to be evaluated to determine the most energy-efficient, feasible flowsheet. Various shortcut methods based on tray-to-tray calculation and pinch point analysis for the inspection of feasibility and the determination of the minimum energy demand (MED) for homogeneous non...

The TraY protein is required for efficient bacterial conjugation by Escherichia coli F factor. TraY has two functional roles: participating in the "relaxosome," a protein-DNA complex that nicks one strand of the F factor plasmid, and up-regulating transcription from the traYI promoter. The traY gene was cloned, and the TraY protein was expressed, purified, and characterized. TraY has a mixed al...

Stroke patients may develop personal neglect, peripersonal neglect or both. Four new measures were tested in a sample of 42 right-handed inpatients (25 male; 17 female, median age 72 years). Participants removed keys from a rack, identified grocery items, washed their face, and cleaned a tray. Prior to this, they were classified as: no neglect (15), personal neglect (8), peripersonal neglect (7...

PURPOSE To compare the extent of tibial bone covered by the tibial tray in 6 most commonly used total knee arthroplasty designs in order to strike a balance between mediolateral cortical fit and optimal tibial component rotation. METHODS In 74 men and 27 women aged 17 to 60 (mean, 32) years with suspected soft-tissue injuries, their magnetic resonance images of the knee in full extension were...

BACKGROUND Different factors such as impression techniques and materials can affect the passive fit between the superstructure and implant. The aim of this study was to determine the effect of different impression materials and techniques on the dimensional accuracy of implant definitive casts. MATERIALS AND METHODS Four internal hex implants (Biohorizons Ø4 mm) were placed on a metal maxilla...

We perform a new analysis of the performance of the wide-band code-division multiple access (W-CDMA) randomized slotted-offset random access channel with Nakagamifading and compare it with the performance of a comparable randomized slotted-ALOHA-based random access channel. In a previous paper, it was shown through simulations that the W-CDMA random access channel is fast, robust, and simple to...

In minor veins of leaves of Beta vulgaris L. (sugar beet) yellows virus particles were found both in parenchyma cells and in mature sieve elements. In parenchyma cells the particles were usually confined to the cytoplasm, that is, they were absent from the vacuoles. In the sieve elements, which at maturity have no vacuoles, the particles were scattered throughout the cell. In dense aggregations...
